Terrestrial modulation (Out Terr)
These options allow configuring the DVB-T/DVB-H modulator of the device.
- Modulation: Output modulation format: QPSK (4 QAM), 16 QAM, 64 QAM.
- Invert (Spectrum inversion): Activate or deactivate the spectrum reverse in the
modulation.
- GI (Guard interval): Allows selecting the guard interval of the modulation: 1/4, 1/8, 1/16 and 1/32.
- BW (Bandwidth): Selection of the Bandwidth of the modulated signal: 8 MHz, 7 MHz and 6 MHz and 5MHz. The 5 MHz
option is only supported by DVB-H standard.
- Tx Mode (FFT Mode): 8K, 4K and 2k. The 4k option is only supported by DVB-H standard.
- FEC: Indicates the relationship between the redundant bits and the transmitted information bits:1/2, 2/3, 3/4, 5/6 y
7/8. For example, in a FEC = 2/3 relation we will find 2 information bits and 1 redundant bit.
- Mode: Selection of the modulation standard: DVB-T and DVB-H.
Note: The output useful bits rate will depend on the following parameters: Bandwidth, guard interval, FEC
codification and modulation. In the
Attachment I
you will find all the information related to the resulting useful bit
rate in each configuration.
Output configuration ( TV output)
In these options you can configure the output parameters of the terrestrial signal.
- RF Channel (MHz): Output frequency of terrestrial modulation. In order to
introduce the frequency, press the “OK” button and the cursor will be placed over
the frequency. With the keys of the cursor, we can move through all the digits and
change the values. Press “OK” in order to save the value. Options: 47-862 MHz.
- RF Level: Regulation of the output level of the modulated signal. Options: 0-15dB.
Summary table:
2. Auto
This option allows saving and loading the configuration of the module in the PRO
201 programmer.
- Read from module: It stores the current configuration of the module in the
memory of the programmer. The steps to make a correct reading of the headend
are specified below:
1. Select the option “Read from
module” through Up/Down buttons.
Press OK to continue
2. Select the position of “CFG”
memory where you wish to save the
current configuration of the module.
3. A window will appear and it will let
you know that the reading made has
been correct
